The 2025 Nobel Prize in Chemistry was awarded to scientists for their groundbreaking contributions to the pioneering research on Metal-Organic Frameworks (MOFs), marking the official entry of these revolutionary materials, often hailed as "Molecular Sponges", into the core stage of technological innovation. MOFs are crystalline porous materials formed by the molecular self-assembly of metal ions/clusters and organic ligands. Their unique "programmable" is driving paradigm shifts in fields such as energy, environment, and healthcare.
Core Performance Characteristics of MOFs
Ultra-High Specific Surface Area
The internal pores of a single gram of MOF material can be unfolded to cover an area of 7,800 m² (equivalent to a football field), providing immense space for gas adsorption.
Supported by: BET Specific Surface Area Analysis (N₂/CO₂ Adsorption, 77K-298K)²
Precisely Programmable Structure
Metal nodes and organic ligands assemble freely like "Molecular LEGO®", enabling pore size customization within the range of 0.5 - 9.8 nm.
Supported by: XRD Crystal Structure Analysis + Small-Angle X-Ray Scattering (SAXS)³
Intelligent Breathing Effect
Pores can dynamically expand by up to 40% (e.g., MIL-53 upon CO₂ adsorption), enabling molecular-level intelligent capture.
Supported by: In-situ XRD/FTIR + High-Pressure Adsorption Analysis⁴
High Density of Active Sites
Surface distribution of 3-5 active sites per square nanometer (10 times greater than traditional catalysts), driving highly efficient catalysis.
Supported by: XPS Valence State Analysis + BET Adsorption Analysis⁵
Thermal Stability Challenge
Potential structural collapse within 5 minutes under moisture exposure (e.g., MOF-5), necessitating rigorous stability validation⁶.
Supported by: TGA/DSC (Humidity Control) + In-situ XRD
Atomic-Level Dispersion
Metal cluster spacing is as small as 1.2 nm, determining catalytic selectivity.
Supported by: HAADF-STEM + Electron Diffraction⁷
Drug Loading Capacity
Single particle drug loading capacity reaches 48 wt%⁸.
Supported by: NMR + Molecular Relaxation Time Analysis
